In enzymology, an allene-oxide cyclase (EC 5.3.99.6) is an enzyme that belongs to the family of isomerases, specifically a class of other intramolecular oxidoreductases. The systematic name of this enzyme class is (9Z)-(13S)-12,13-epoxyoctadeca-9,11,15-trienoate isomerase (cyclizing).
The allene oxide of linolenic acid (i.e., (9Z)-(13S)-12,13-epoxyoctadeca-9,11,15-trienoate) is converted by allene oxide cyclase to jasmonic acid ((15Z)-12-oxophyto-10,15-dienoate).[1]
Structural studies
As of late 2007, 6 structures have been solved for this class of enzymes, with PDB accession codes 1Z8K, 1ZVC, 2BRJ, 2DIO, 2GIN, and 2Q4I.
